• Catalyst-Controlled Regiodivergent CH Borylation of Multifunctionalized Heteroarenes by Using Iridium Complexes

  The regiodivergent CH borylation of 2,5‐disubstituted heteroarenes with bis(pinacolato)diboron was achieved by using iridium catalysts formed in situ from [Ir(OMe)(cod)]2/dtbpy (cod=1,5‐cyclooctadiene, dtbpy: 4,4′‐di‐tert‐butyl‐2,2′‐bipyridine) or [Ir(OMe)(cod)]2/2 AsPh3. When [Ir(OMe)(cod)]2/dtbpy was used as the catalyst, borylation at the 4‐position proceeded selectively to afford 4‐borylated products

  regiodivergent C中的 ħ硼化与双的2,5-二取代的杂芳烃（频哪醇）二硼通过使用原位形成的从物[Ir（OME）（COD）]铱催化剂达到2 / dtbpy（COD = 1,5-环辛二烯， dtbpy：4,4'-二-叔丁基-2,2'-联吡啶）或物[Ir（OME）（COD）] 2 /2 ASPH 3。当使用[Ir（OMe）（cod）] 2 / dtbpy作为催化剂时，在4位进行的硼化选择性进行，从而以高收率提供了4硼化的产物（dtbpy体系A）。所述的[Ir（OME）（COD）]时改变区域选择性2 /2 ASPH 3中使用过的催化剂; 以高收率和高区域选择性获得了三硼化产物（AsPh 3系统B）。硼化的区域选择性很容易通过改变配体来控制。通过使用相同的起始原料，该反应被用于合成两种不同的生物活性化合物类似物。

  Novel linkers for linking a donor dye to an acceptor dye in an energy transfer fluorescent dye are provided. These linkers faciliate the efficient transfer of energy between a donor and acceptor dye in an energy transfer dye. One of these linkers for linking a donor dye to an acceptor dye in an energy transfer fluorescent dye has the general structure R 21 Z 1 C(O)R 22 R 28 where R 21 is a C 1-5 alkyl attached to the donor dye, C(O) is a carbonyl group, Z 1 is either NH, sulfur or oxygen, R 22 is a substituent which includes an alkene, diene, alkyne, a five and six membered ring having at least one unsaturated bond or a fused ring structure which is attached to the carbonyl carbon, and R 28 includes a functional group which attaches the linker to the acceptor dye.
